  • Preparation of the water phase For preparation and pasteurizing of the water phase the mixing, dispersing and homogenizing device was used. This device had a 25 litre thermally controlled vessel with a scraped anchor agitator. During dissolving/dispersing of the dry materials of the water phase in the water, the mixture is circulated continuously and temperature of the water phase is monitored in-line in the mixing zone of the colloid mill. The mixture was pasteurized at 70 °C during 10 minutes. Afterwards the water phase was cooled down till approximately 55 D C without mixing. Preparation of the fat phase During stirring, all ingredients of the fat phase were molten under nitrogen atmosphere, and heated till about 80 °C. Afterwards, the fat phase was cooled down under continuous stirring till 55 °C.
  • Emulsification The water phase was added slowly to the fat phase under intensive stirring and emulsified to a water-in-oil emulsion. During emulsification the emulsion was tempered at 55 °C for at least 30 minutes. Processing A 30 kg-batch size was employed. The mix was stirred for 15 minutes before pumping. After pumping, the line was allowed to run for 15 minutes before any collection of product. During processing, the mass flow was fixed at approximately 50 kg/h. At the indicated measuring points the temperature was measured. When a stable situation was reached, 15 tubs were filled with approximately 125g margarine. The following process parameters (temperatures in °C) were recorded:
  • the results of the product evaluation are given in table below.
  • the spreads containing pine needle extract had a higher c-value for hardness than standard spreads. All samples spread easily with no apparent water loss.
  • the spreads of the invention had, in addition to increased hardness, good spreadability, good structure, good tailing and good sticking to the knife.
